FIELD OF THE INVENTION

The present invention relates to doorbells and, more particularly, to methods of selectively enabling and disabling a doorbell remotely via a mobile device.

BACKGROUND OF THE INVENTION

A doorbell is a signaling device that sounds an alarm for alerting an occupant of a building, when a visitor presses a button near an entry door to the building. The alarm issued by the signaling device of a standard doorbell is sufficiently loud to ensure that an occupant of the building can be alerted to the presence of a visitor when the doorbell button is pressed.

A doorbell enables a visitor to alert one or more occupants of a building to their calling from an entry door. However, a sounding doorbell can awaken a sleeping occupant unwantedly, such as during standard sleeping hours or during a daytime nap. Children often nap during the day, and are frequently awakened by sounding doorbells. Although doorbells are important for alerting a building occupant to calling visitor, there is a need in the art for a doorbell that can be selectively silenced when desired, such during standard sleeping hours, during naps, and at other selected times when being disturbed by a sounding doorbell is unwanted.

FIGS. 3-14 illustrate a sequence of steps of converting a standard, prior art doorbell circuit 301 of a standard, prior art doorbell 300 in FIG. 3, to a controller doorbell circuit 401 of a controller doorbell 400 in FIG. 14 in accordance with the principle of the invention. The method of converting doorbell 300 of FIG. 3 to controller doorbell 400 of FIG. 14, namely, converting doorbell circuit 301 of FIG. 3 to controller doorbell circuit 401 of FIG. 14, initially begins by providing standard, prior art doorbell circuit 301 of standard, prior art doorbell 300, and, according to the principle of the invention, controller 102. In FIG. 12, controller 102 is wired to battery power source 340 and includes printed circuit board 341 that mechanically supports and electrically connects input transformer terminal 342, output transformer terminal 343, alarm terminal 344, and switch 346. In FIG. 3, doorbell circuit 301 is a standard, prior art, one-button doorbell circuit 301, including a doorbell button 302 having first terminal 303 and second terminal 304, a transformer 305 having first terminal 306 and second terminal 307, and signaling device 310 having transformer terminal 311 and alarm terminal 312. First terminal 303 of button 302 is wired to first terminal 306 of transformer 305 via wire 320, second terminal 307 of transformer 305 is wired to transformer terminal 311 of signaling device 310 via wire 321, and second terminal 304 of button 302 is wired to alarm terminal 312 of signaling device 310 via wire 322. Wire 320 wires first terminal 303 of button 302 directly to first terminal 306 of transformer 305, wire 321 wires second terminal 307 of transformer 305 directly to transformer terminal 311 of signaling device 310, and wire 322 wires second terminal 304 of button 302 directly to alarm terminal 312 of signaling device 310. Doorbell circuit 301 is closed activating signaling device 310, when button 302 is pressed. Doorbell circuit 301 is open deactivating signaling device 310, when button 302 is released. Button 302 is a standard, single-pole, single-through pushbutton switch that momentarily closes doorbell circuit 301 when button 302 is pressed. Transformer 305 steps down the 120 or 240-volt AC electrical power from the building's AC mains input to a lower voltage, typically 10 to 20 volts, which is supplied to signaling device 310.

Signaling device 310 sounds an audible alarm when button 302 is pressed. Button 302 is mounted exteriorly near an entry door to the building, which is a house, an apartment, or other chosen building. Signaling device 310, which is a standard chime, a standard bell, or a standard buzzer, is mounted inside the building. The audible alarm sounded by signaling device 310 is a sound of one or more musical notes, when signaling device 310 is a chime. The audible alarm sounded by signaling device 310 is a sound of one or more ringing bells, when signaling device 310 is a bell. The audible alarm sounded by signaling device 310 is a buzzing sound, when signaling device 310 is a buzzer. The audible alarm issued by signaling device 310 is sufficiently loud to ensure that one or more occupants of the building are alerted to the presence of a calling visitor at the entry door when button 302 is pressed. In this example, signaling device 310 is a standard chime, including two flat metal bar resonators 330, which are struck by plunger 332 operated by a solenoid. Resonators 330 are tuned to selected notes. When button 302 is pressed closing doorbell circuit 301, the solenoid of signaling device 310 actuates plunger 332, which strikes one of resonators 330, such as resonator 330A. When button 302 is released opening doorbell circuit 301, a spring 333 on plunger 332 pushes plunger 332 in the opposite direction, causing it to strike the other one of the resonators 330, namely, resonator 330B. This creates a standard two-tone or “ding-dong” sound.
